Christie Hefner, former CEO of Playboy and an associate of the Center for American Progress, made this outlandish claim on Morning Joe today: “Last year we hit a record number of murders from guns, and this year we’re already outpacing last year’s number. Now, there are contributing factors that are not under anybody’s control, it may seem odd, but it’s factually true, one of them is actually the weather. There is a dramatic increase in gun violence when it is warmer, and we are having this climate change effect that is driving that.”
